Introduction

OWL Classes

There are currently eight classes in the ontology, each of which represents an entry in the DRS as well a two object properties to link sensors and platforms.

OWL Classes

Concept Schemes

The named individuals of each class are also represented as concepts in SKOS concept schemes: data type, ecv, frequency, institutes, platforms, processing levels, products, and sensors. The use of a concept scheme allows easy navigation up and down the tree as well as providing relationships to concepts from other DRS. As well as relationships between sensors and platforms, each ECV concept is related to one or more data type concepts.

Reconstructed unprocessed instrument data at full resolution, time referenced, and annotated with ancillary information, including radiometric and geometric calibration coefficients and georeferencing parameters, computed and appended, but not applied, to L0 data.

Geophysical variables derived from Level 1 source data at the same resolution and location as the level 1 data, typically in a satellite projection with geographic information. These data form the fundamental basis for higher level CCI products.
